Try out GNOME's New Window Focus Animation in Ubuntu 22.10/Fedora 37
Gnome, the default desktop environment in Ubuntu & Fedora Workstation, is going to replace the app menu with a new window animation, for indicating window focus.
Meaning it will remove the app menu for current window, in the top-bar beside ‘Activities’ button. Because, it’s always confusing users who are new to GNOME.
